 Sigma APO 120-300mm F2.8 EX DG OS HSM lens : Sigma announces the new Sigma APO 120-300mm F2.8 EX DG OS HSM lens. This new Sigma lens incorporates Sigma’s proprietary Optical Stabilizer system, and offers high image quality. In addition, the Sigma APO 120-300mm lens features splash proof design for use in harsh conditions. One SLD and two FLD glass elements are used for maximum correction of chromatic aberrations. The Super Multi-Layer Coating reduces flare and ghosting, and the lens design incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range. Improved optical performance provides excellent correction of sagittal coma flare, and ensures ultra-high resolution, comparable to a fixed focal length lens.
